Moments after a plane plummeted into her Connecticut home last week, Joann Mitchell was made a wrenching call to 911 in which all she could do was scream with grief over the tragic death of both her daughters.

Sadie Brantley, 13, and her infant sister Madisyn Mitchell, 1, were instantly killed when a private plane fell from the skies above their East Haven home.

As flames engulfed the back of he house and cut off any hope of pulling out her girls, Mitchell wailed to rescue operators but could barely form a sentence. 'Oh god no! Oh god no!' were all the words that came out in her brief call.

Other calls were made, including one from a neighbor who told operators that 'a woman is saying that she has two women in the back room where the plane is.'

More horrific screams can be heard in the background.

'The only thing she kept saying was, "I’m not going to leave until we find my girls, you have to find my girls,"' a man at the scene told WFSB.

The two young children were killed when a 10-seater propeller plane piloted by former Microsoft executive Bill Henningsgaard crashed into the home.

Joann Mitchell, 39, mother of the two girls, tried to rescue her children from the house after escaping herself, but was unable to compete with the flames

Henningsgaard's 17-year-old son was also in the plane and both he and his father died in the crash.

Mitchell, 39, escaped unharmed, but was unable to save her two children.

Neighbors tried to save her girls, but were unable to enter the home due to the engulfing flames.

Henningsgaard, a 54-year-old
father of three from a prominent Astoria family, had been visiting
Yale College with his only son, age 17, when their aircraft missed the
runway at Tweed New Haven airport and crashed at about 11.30am.

The funeral for the sisters is scheduled
for 10 a.m. at Trinity Temple Church of God in Christ in New Haven,
according to their aunt Lawanda Middleton.

Middleton, who runs a church in
Hamden with her husband, said Monday that her family wasn't releasing
any information but may do so later.

'My family's just grieving right now,' she said.

Madisyn Mitchell, 1,was killed along with her 13-year-old sister inside their East Haven home when a plane crashed down on it, engulfing the house in flames

A
friend of 13-year-old Sadie, Autumn Hernandez told the paper that Mrs.
Mitchell was close to her girls, who were often left alone together
while Mitchell, a single mother, worked.

'Sadie
was one of my best friends,' Hernandez said in an interview with The New York Post. 'The Mitchells] were a really
tight family. ... Sadie and her mom were so close. Her mom was always
working as a nurse and it was hard for her because she's a single mom,
so Sadie would babysit her little sister all the time. She loved it
though. I'm really going to miss her.'

The two
girl's bodies were visible in the wreckage of the East Haven home but they
could not yet be reached initially because the building was unstable, Fire
Chief Douglas Jackson told theSeattle Times.

It
is believed the bodies of two of the victims were in the basement of
the house, which was filled with water. The plane's fuselage was wedged
inside one of the houses.

A priest was reported to be trying to comfort Mrs. Mitchell. Neighbors said she had only recently moved to the area.

Mr Henningsgaard was
flying his Rockwell International Turbo Commander 690B from New
Jersey's Teterboro airport to Tweed New Haven Airport, the Federal
Aviation Administration said.

The cause of the crash remained under investigation. Officials with the National Transportation Safety Board said the plane, a Rockwell International Turbo Commander 690B, was upside down when it hit the houses at a 60-degree angle, and the pilot didn't declare an emergency before the crash. A preliminary NTSB report is expected within two weeks.

The two heavily damaged homes, which caught fire after the accident, were expected to be torn down.

Investigators from the National

This was not the former Microsoft executive's first accident. The New York Post reported that In 2009, he crashed his plane into the Columbia River in Washington state with his 84-year-old mother on board.

In a Facebook post last year, the 54-year-old father of three joked about having to buy another plane 'to replace the one that turned out not to be amphibious.'

Henningsgaard blamed the crash on engine failure, explaining in a blog entry that 10 minutes into the flight, the plane motor 'coughed briefly' and then died seconds later.

‘The plane was starting to pitch forward, being pulled toward the bottom by the heavy engine, causing the wing we were standing on to start to tilt,’ he wrote. ‘When the plane went nose-down, we’d be in the water. I’d like to tell you I felt brave and confident at that moment, that I knew we’d make it.

He went on to say that he felt fear of ‘exhaustion and panic and very possibly death as we tried for shore.

‘We
haven't recovered anybody at this point and we presume there is going
to be a very bad outcome,’ East Haven Fire Chief Douglas Jackson said.

Neighbor David Esposito, said he heard a woman screaming that her children were inside the burning home.

He said he ran into the upstairs
of the house, where the woman believed her children were, but they could
not find them.

They returned downstairs to search but he dragged the
woman out when the flames became too strong. 'It's total devastation in the back of the home,' he said.

Angela Wordie was on her deck taking in towels when she noticed a plane making a strange sound.

'It kind of was gliding. The next thing I know it hit the house,' she told NBC Connecticut.

Wordie added that she saw a woman kneeling on the front lawn of 64 Charter Oak Avenue, screaming, 'My children!'

Another neighbor, Diane Carr, recalled the moment when she felt her house vibrate as Hennigsgaard's plane approached the street. With the neighborhood’s close proximity to the airport, she had initially thought nothing of it.

‘I ran outside,’ she told the New Haven Register. ‘We started to see smoke, and then we heard explosions. Then we heard popping sounds afterwards.’

The FAA said it is investigating the cause of the crash.

Mr Henningsgaard was the son of a former Astoria mayor and the brother of the Oregon city's district attorney, according to the Daily Astorian.

Blair Henningsgaard, the victim’s brother, said the 54-year-old retired from Microsoft years ago and dedicated his life to helping underprivileged youth through Eastside Pathways, a non-for-profit organization he had set up.

Seattle-based non-profit organization Social Venture Partners confirmed the death of board member Mr Henningsgaard in a tribute on its website.

'There
are hundreds of people that have a story about Bill - when he went the
extra mile, when he knew just the right thing to say, how he would never
give up,' SVP said in a statement. 'He was truly all-in for this
community, heart, mind and soul.'

Max, 17, was due to be a senior at independent Seattle school Lakeside. He had
traveled to the East Coast with his father so they could look at
colleges, including Yale, according to NBC.

Mr
Henningsgaard, who worked at Microsoft for 14 years before following a
career in philanthropy, had survived a plane crash with his mother,
Edna, a former Astoria mayor, in 2009.

A boat had to rescue them from the Columbia river after their light aircraft plunged into the water.

At
the time, a sheriff said they had been flying at 8,000ft when the
engine suddenly cut out, forcing them to land in the river, according to
KVAL.

A vigil for the victims of the plane crash is scheduled for Saturday night at Margaret Tucker Park in East Haven, according to the Post.
